Question

In a computer lab, there are $3$ computers for every $6$ students. How many computers will be needed for $24$ students?

Answer 1

Determine the number of computers:

It is given that, the number of students is $6$.

The number of computers required for $6$ students is $3$.

The number of computers required for $1$ student is $\frac{3}{6}$. [By unitary method]

The number of computers required for $24$ students is $\frac{3\times 24}{6}=\frac{72}{6}=12$.

Therefore, the number of computers required is $\mathbf{12}$.
